Customer Reviews for Thompson's One Coat Damp Seal 2.5Ltr
"Surprisingly easy to apply. I used a roller and obtained a good solid smooth coat. I was very impressed with the final result. Good and solid in a few hours and proved to be an excellent base for emulsion. The only warning on this is that the stated coverage is somewhat optimistic. I used 2.5 litres to cover a 5m wall. That's about 5m² per litre, not the stated 7m². Certainly did the trick though and was well worth the expense. No sign of any marking to date. This is an excellent, easy to use product."
"First time I've used this product. Been struggling to cover damp patches on an internal wall. Dubious to start but so far so good. Apply liberally as instructions, but you will need to lay off a few times as the product dries to avoid sags. All spots that initially bubbled up dried back rock hard and did not open up. Then easily over painted with emulsion and whole wall dried consistently and no dark damp patches. Permanently in the van now!"
"Great product to sort the problem fast. Couldn't be more easy than roll it on the wall, after you have eliminated the cause of the problem. Ideal if you have no cavity. Checked with the damp meter and a greatly reduced reading was given. Best way to apply is with gloss 4" roller for speed and best coverage and where a glove as it doesn't wash off !!"
"Found product was very difficult to apply,did not fully cover the water marks on ceiling,did not want to adhere to ceiling properly.After wasting a lot of my time took product back to Scewfix who gave me a full refund."
